Letters Patent No. 113,464, dated April 4, 1871.-

IMPROVEMENT IN CUTTER-HEADS.

The Schedule referred to inthese Letters Patent and making part ot the same.

lmeut in cutter-heads for cutting or forming round rods of wood for hanging window-curtains and for various other purposes 5' and It consists in a revolving feeding-disk or cutter,"and mode of holding and adjusting the salue, and the inanner of forming and holding the shaping-cutters, and in the arrangement and combination of parts, as hereinafter more-fully described.

In the accompanying drawing-.-

Figure 1 represents a horizontal section of the cutter-head taken ou the line a: x of fig. 2.

Figure 2 is a top view. Y

Figure 3 is a longitudinal section'of tig. l on the line y y.

Figures 4 and 5 are 'views of the opposite sides of the head, both views showing the mode of holding the shaping-cutters, and the latter .the inclined position of the revolving disk-feeder.

Similar letters of reference indicate corresponding parts. p

'A is the shank of the cutter-head, which tits a holiow spindle which drives the head.

B is the headproper, on which the shaping-knives or cutters are supported. j

There are two of these knives or cutters, C and D, confined to the head bya single screw. as seen in figs. 4 and 5. Y L i y It will be noticed that the cutter D stands atan angle to clip 0E the wood andbring the stick to near therequired size, while the face or edge of the other cutter stauds'paraliel with the rod and gives the latter its true size and shape and a smooth surface.

E, fig. 2, represents the stick which is being cut.

These sticks are usually sawed out square, and are cut into a round shape in passing through the head.

In a slot, F, formed in the head I place the revolving feeding cutter-disk Gr.

As the stick ofv wood is introduced into the head through its funnel-shaped mouth H the edge `of the feeding-cutter G works on to it as a' screw, forming a spiral cut around thevstick. i This is done by virtue of the angle at which the cutter is placed withregard to the line of motion, as plainly seen in iig. 5. Thel stick is therefore forced up to the shaping-cutters C D by a continuous screw-thread. 4

I is a block of metal, having a lug or vpivot upon its side, upon which the feeding-disk G revolves.

' The block I is held to the head bythe screw J, and the disk is made `adjustable so as to penetrate the wood more or less by means of the slot-hole in the block througlrwhich the screw J passes, (seen-iu iig. 3.)

.It will he seen that the shaping-cutters C D are fastened Orheld tothe head by the thick angular washer K.

The fastening-bolt L passesdown between the two cutters, so that the latter are made without slots, which greatly simplifies and cheapens theni, while they are held andy adjusted quite as effectually and completely as they' could be if made with slots in the ordinary manner.

Having thus described 1ny invention,

I claim as new and desire to secure by Letters4 scribed.-

2. The combination of the feeding-disk G, support ing-block I, cutters C and D, and washer with the head B, arranged and operating substantially as and p for the purposes described.
